A roller coaster is a good example for motion. I've chosen three points from the roller coaster and there are point 1, point 2, and point 4. The roller coaster starts with no KE and some GPE because it needs to get to the top of the hill. At point 1 it haze the most GPE because it is the heist point. Now the amount of KE is the least because it is the lowest it cane go. At point 2 it haze the least amount of GPE it haze the lowest is can go. For the amount of KE is the most because it is the heist it cane go. At point 4 for the amount of GPE it is increasing because it is not all the way to the top yet. Now the amount of KE it is decreasing because it is loosing KE. KE is the heist when it is Lowe to the grown. GPE is the heist when it is at the top. The only time that they are the same is when that they are in the middle.
